DRUM-T'UG.

SPECIFICATION forming part of Letters Patent No. 730,008, dated June 2,1903.

Application filed March 4, 1903. Serial No. 146,114. (No model.)l i

To (bZZ'wz/om/ it may concern:

Be it known that I, XVALLACE R. DUNBAR, a citizen of the United States,residing at Everett, county of Middlesex, State of Massachusetts, haveinvented certain new and useful Improvements in Drum-Tugs, of which thefollowing is a specification, such as will enable those skilled in theart to which it ap pertains to make and use the same.

This invention relates to tugs for drums having a loop sliding upon thestraining strings or cords, by means of which the heads of the drum maybe tightened or loosened; and the object thereof is to provide animproved device of this class which is simple in construction andoperation and which will not slip, and thus permit the strings or cordsto become slack. l

The invention is an improvement on that described and claimed in UnitedStates Letters Patent No. 300,469, dated October 2, 1888, and is fullydisclosed in the following speciication, of which the accompanying'drawings form a part, in which the separate parts of myimprovement aredesignated by suitable reference characters in both of the views, and inwhich- Figure l is a perspective view of a drum provided with myimproved tug, and Fig. 2 a perspective view of the tug detached.

In the drawings forming part of this specification I have shown at a adrum of the usual form, and this drum is provided with tugs l? madeaccording to my invention, said tugs being used in connection with thestraining strings or cords c. The tugs l) may be composed of any desiredmetal, and, as in the patent hereinbefore referred to, consist of a looplf2, open at the back, as shown at b3, whereby two hooks h4 are formed,and said l loop is provided with a downwardly-directed ture or openingb3 between the ends of the hook-shaped members h4 of said loop, and saidtugs may be drawn down upon the strings or cords for tightening them andupwardly for the purpose of loosening said strings or cords by means ofthe tongue or flap 115. The loopA b2 may loe made of any desired formorornamentation, and the back portion of said loop may be of any desiredlength, and the said loop may thus be given the desired strength anddurability, and the opening b3 being at the back of the loop b2 the tugsmay easily be slipped on or otf the strings or cords. All these featuresof construction are the same as those in the patent hereinbeforereferred to; but in my invention l form on the front of the loop b2 anupwardly-directed extension d, having a cross-head cl2, which, as shownin the drawings, is secured thereto by a screw or other device d3; butsaid cross-head may be formed integrally with the upwardly-directedextension d if desired, and said cross-head. is provided in its oppositeends with vertically arranged grooves dthroughwhich the strings or cordsc are passed. The cross-head d2, around which the strings or cords c arepassed, forms a spreader for said strings or cords and prevents the tugsfrom slipping, as will be readily understood, said strings or cordsbeing held or bound between said cross-head and the loop b2. Asheretofore constructed the tugs after they become a little worn wouldslip on the strings or cords and could not be retained in place, so asto give the desired tension to said strings or cords, and this resultedin great inconvenience and trouble; but with my improvement the stringsor cords are forced apart immediately above the loop 112 and heldtightly against the sides of said loop, thereby avoiding the slipping ofthe tugs on the strings or cords and holding them securely in place.

My improvement does not add materially to the cost of these tugs asformerly made and is perfectly adapted to accomplish the result forwhich it is intended, and changes in and modifications of theconstruction herein described inay be made without departing from thespirit of my invention or sacrificing its advantages.

IOO

Having` fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A drum-tug` consisting of a loop open at one side and provided with alining Which is secured to the closed side thereof and which projectsbelow said loop, the closed side of said loop being,` also provided withan upwardly-directed extension having' a cross-head provided withgrooves in its opposite ends, substautially as shown and described.

2. A drum-tug comprising a central loop open at one side and providedWith a leather lining which is secured therein and which is also open atsaid side, and provided With a doWnWardly-directed extension, the loopbeing provided at the closed sidc with an up Wardly-directed extensionhaving,` a crosshead at its upper end, substantially as shown anddescribed.

3. In a device of the class described, a loop open at one side, andtheclosed side of which is provided with an upwardly#directed eXtensionhaving a cross-head provided at its opposite ends with verticallyarranged grooves, substantially as shown and described.

In testimony that I claim the foregoing as niy invention I have signedmy name, in presence of the subscribing;` Witnesses, this 21st day ofFebruary, 1908.
